Plug the adapter into the wall outlet or power strip. If using a power strip, make sure the strip is on. Most laptop power adapters have a small LED light; the light will illuminate when power is being transferred from the outlet to the adapter. If the light illuminates, chances are you have sufficient power to supply your laptop. Wiggle the power cord if the LED light did not initially illuminate. If the light turns on and off when you wiggle it, you might have a loose cord in the adapter, or the outlet could be faulty. Plug the adapter into another power outlet, preferably a different circuit in another room, if the LED light did not illuminate the first time. If it lights up from the second outlet, the first outlet either does not work or other devices were using too much power on the initial circuit. Connect the other end of the adapter to the laptop and turn the laptop on. When the computer starts up, you should see an indication of how the laptop is being powered in the lower right-hand corner. If you see a battery icon, then the laptop is being powered by the battery, not the adapter. Make sure both ends of the adapter are securely connected. If they are, and if the LED light on the adapter is lit, then you likely have a faulty wire that is not properly connecting to your computer. If you see a plug or adapter icon, then the laptop is successfully being powered by the adapter. If the LED light on the adapter is not lit, then the bulb is out, but the adapter is still working.

I see that you are experiencing issues with your Laptop, you mentioned that the battery has %40 charge and that the adapter is plugged in on the laptop to the wall but still you get an orange light, but when you press the power button nothing happens on the machine.

Remove the battery and the adapter from the Laptop then press and hold down the power button, this is to drain power from the motherboard.

Once the power has been drained from the Laptop, connect the adapter back again but leave the battery out of the machine, then turn the system ON using the Adapter only.

If the Laptop turns ON using the adapter only then it is possible something is wrong with either the Battery or the motherboard of the Laptop.

Turn the Laptop OFF again then put the battery back in, then power the system again check if it will turn on with the battery and adapter in the Laptop.

If the Laptop does not turn ON when the battery is plugged in then you will need to have the system checked for a motherboard issue.
